Measurements on O21Δg and O21Σ+g in discharge flow systems

Abstract

The absolute intensity of dimole emission at 6340 A by two O21Δg is found to be 16±4 [O21Δg]2 in cm3 mol–1 s–1 units. The rate constants for their energy pooling to yield O21Σ+g, ν= 0 and 1 are (1.2±0.3)× 107 and 6 × 105 cm3 mol–1 s–1 respectively. The removal of O21Σ+g at the walls is partly diffusion controlled, rate constants for its deactivation by H2O and H2 are reported.
